Question

请任何人帮我做对象数组验证...权重是我的字段名称..我只想验证（存在和数字）权重。但我无法得到任何验证错误..我不知道在whivh地方，我做错了..如果有人知道解决方案请让我知道

这是我的观点：

<tbody>             
            <% if @company_column_master != nil then                            
                @company_column_master.each.with_index(0) do |assess,index| %>
                  <tr> 
                    <td><%= index+1 %> 
                        <%= hidden_field_tag :company_column_master_id ,assess.attributes["company_column_master_id"],name: 'cd_column_id[]' %>
                        <%= hidden_field_tag :data_element_id ,assess.attributes["data_element_id"],name: 'data_element_id[]' %>
                        <%= hidden_field_tag :display_order ,assess.attributes["display_order"],name: 'display_order[]' %>
                    </td>       
                    <td><%= text_field_tag "display_name", assess.attributes["display_name"], name: 'display_name[]', size:50 ,:autocomplete => :off%></td>
                    <td><%= text_field_tag "weightage", assess.attributes["weightage"] ,name: 'weightage[]' ,:autocomplete => :off%></td>                                           #getting values from db using array
                    <td class="text-center">
                        <%= check_box_tag('status'+index.to_s,'1',if (assess.attributes["status"] == 1) then true end, class: 'js-switch') %>
                    </td>
                  </tr>
                <%end%>
                <%= hidden_field_tag :phase_id ,@company_column_master[0].attributes["cd_phase_id"]%>
                <%= hidden_field_tag :phase_detail_id ,@company_column_master[0].attributes["cd_phase_detail_id"]%>         
            <%end%>
        </tbody>

这是我的模范部分：

class CompanyColumnMaster < ActiveRecord::Base
  validates :weightage, :presence => {:message => 'cannot be Blank!'}, :format => {:with => /\A[0-9]+\z/, message: "may only contain numbers."}, 
  :length => {:maximum => 50, :message => 'Exceeds Maximum number of numbers.'}

  validate :check_weightage

 def check_weightage
   if weightage!=nil && weightage < 0
     errors.add(:weightage, "should be greater than or equal to zero")
   end
 end
end

你正在做两件事 - 你使用Rails＆＃39; validates和自定义validate。选择一个。

为了使用自定义验证，你必须编写方法（你已经做了几乎好的）：

validate :check_weightage

def check_weightage
   errors.add(:weightage, "should be greater than or equal to zero") unless (weightage && weightage >= 0 && weightage.is_a? Integer)
end

验证活动记录中的数组对象
